3 questions on Ohio’s own driver fitness rules
These differ from the rules that hold nationally — they are the ones that catch out drivers who studied another state’s handbook.
1. In Ohio, a person under 21 may not drive with a whole-blood alcohol concentration of at least:
- A0.05%
- 0.02%
- C0.01%
- D0.08%
Answer: 0.02%. Ohio Revised Code §4511.19 prohibits a person under twenty-one from operating with at least two-hundredths of one per cent (0.02%) by weight per unit volume of alcohol in whole blood (with parallel breath/serum thresholds).

- A0.05% or more
- 0.08% or more
- C0.10% or more
- D0.02% or more

- B10 p.m. and 5 a.m.

2. Driving while very angry or upset is dangerous because strong emotion:
- AHas no measurable effect
